checking Donepezil and Huperzine A: no hard conflicts (1 to watch), but the amber pairs carry interactions to be careful with.
stacking cholinergics (an acetylcholinesterase inhibitor plus another cholinergic or a choline source) can push acetylcholine too high; the classic result is headache, nausea, brain fog, or a low, flat mood.
